This rotary Other objects of the invention will appear as member comprises a shaft I! mounted in the 55 outer breast parallel to the axis of rotation of the saws and offset outwardly from the upper ends of the ribs II, and a plurality of rotary elements l9 mounted on said shaft to rotate therewith. Said elements each comprise preferably a hub member 18 and a disc 19 extending radially from said hub member, said disc having the teeth or serrations 20, which serrations extend a short distance between the saws.

On account of the offset position of the rotary member I6, it preserves the complete lateral openness of the space I3, crosswise of the saws,

while at the same time functioning as an effec: tive baffle barrier to prevent hulls and other debris being thrown into said space.

The rotary member It has still another important function. It is suitably driven so as to rotate in a counterclockwise direction, that is to it from the saws, and permitting it to enter into the roll box past the teeth 2| ofthe seed guard 22.

A certain amount of the cotton thus wiped off of the saw blades will cling to the rotary elements l9. If not removed, it might become J packed and overheated by frictional engagement of the saws therewith. The invention, therefore, provides the cleaning rake 23 having a series of teeth 24, which lie between the rotary elements IS in a position to clean them of adherent cotton.

It will be understood to those skilled in the art that the specific details of construction and arrangement of parts as herein illustrated and described are by way of example and not to be construed as limiting the invention which is described in the appended claims.

What I claim as my invention is:

1. In a huller gin of the-type comprising an outer huller breast cooperating with an inner ginning breast to form a roll box between their This causes the interdigitating portions upper portions and having ribbed lower portions forming between them a seed duct, with gin saws operating between the ribs, the ribs of the huller breast terminating below the rims of the saws in the upper quadrants of the saws forming unobstructed passages between the saws, to the roll box, a rotary member carried by the huller breast on an axis parallel to the axis of the saws, positioned outwardly of said unobstructed passages, including elements with serrations extending between the saws whose paths of rotation lap the saw rims, and a fixed member having teeth projecting between the elements having serrations,

forclearing cotton from between said elements.

2. In a huller gin of the type comprising an outer huller breast cooperating with an inner ginning breast to form a roll box between their upper portions, and having ribbed lower portions forming between them a seed duct, with gin saws operating between the ribs, the ribs of the huller breast terminating below the rims of the saws in the upper quadrants of the saws forming unob- -structed passages between the saws, to the roll box, a rotary member carried by the huller breast on an axis parallel to the axis of the saws, positioned outwardly of said unobstructed passages, including elements with serrations extending between the saws whose paths of rotation lap the saw rims, said rotating member bein driven in the same direction as that of the saws whereby it functions to wipe cotton from the saws, and a relatively fixed member having teeth projecting between the elements having serrations, for clearing cotton from between said elements,

3. In a huller gin of the type comprising an outer huller breast cooperating with an inner ginning breast to form a roll box between their upper portions and having ribbed lower portions forming between them a seed duct, with gin saws operating between the ribs, the huller breast ribs comprising a set of stationary short ribs between the lower portions of said saws, and rotating ribs above said stationary ribs between said saws, and a fixed member having teeth projecting between said rotary ribs for clearing cotton from between said ribs.
